6 Claims.

This invention relates to winding machines for winding yarn with what iscommonly referred to as the open wind or Foster wind on cores of cones,tubes and the like and wherethe cone or tube produced by the machine isknown as a package, and in particular a yarn winder that winds yarnevenly with the yarn tight at the ends and also throughout theintermediate portions of the cones or tubes.

The combination of the continuously traveling yarn guide on the traversewith large cylinders. and with the tubes and cones driven by surfacecontact with the cylinders makes it possible to wind, at high speeds,the same number of yards of yarn per minute continuously and eliminatebuilding up or ribboning.

In winding yarn With conventional winders the speed of winding islimited to a safe operating speed of the traverse and yarn guide,operated by the traverse; as in reversing the direction of travel of theguide it is necessary for the guide to stop and start back in theopposite direction.

The quantity of yarn wound by machines of this type is, therefore,controlled by the operation of the traverse. The yarn is fed from theyarn guide to tubes and cones over a cylinder, and with the surface ofthe cylinder contacting the peripheral surface of a cone or tube, thesurface speed of the cone or tube corresponds with that of the cylinder.

Increasing the diameter of the yarn feeding cylinder, therefore, makesit possible to speed up yarn winders for this use whereby the quantityof yarn wound on a winder is increased from that of conventionalwinders.

In addition to speeding up the quantity of yarn wound per day the largefeeding cylinder in combination with the yarn guide and traverse whereinthe yarn guide is actuated by the traverse makes it possible to obtainan even tight wind with all spongy portions, particularly at the ends,eliminated and with the breaking of the yarn reduced to a minimum.

The purpose of this invention is to improve yarn winding machines andprovide a machine which winds the yarn with a smooth easy pull on theyarn whereby maximum tension may be used and wherein cones or tubesformed on the machine are firm throughout the intermediate parts andalso at the ends thereof.

With the conventional method of winding yarn to form cones and tubes,the yarn winds tight or firm at the center or through the intermediatereverse action at the ends the ends are soft or 2 spongy and this makesit difficult to feed the yarn evenly from the spools, cones, or tubes onunwinding.

With this thought in mind this invention contemplates a winder includingthe combination of grooved cylinders and a traverse, in which thetraverse is provided with a traveling thread guide which carries theyarn and lets the yarn fall into grooves at each of the ends of thecylinders in each revolution of the cylinders whereby the length andsize of the package is substantially unlimited.

The object of this machine is, therefore, to provide means formaintaining constant and maximum tension on yarn being wound on conesand tubes whereby the cones and tubes are tight and firm throughout thelength thereof.

Another important object of the invention is to increase the diameter ofthe yarn feeding cylinders of winding machines whereby the surface speedofv the cylinder is increased while the yarn vided for stopping theoperation of the machine as the yarn breaks.

Another obiect of the invention is to provide an improved yarn windingmachine wherein finished cones or tubes are automatically elevated whencompleted.

A further object of the invention is to provide an improved machine forwinding cones, tubes, and the like with the cones, tubes and the likefirm throughout the length thereof, in which the machine is of a simpleand economical construction.

With these and other obiects and advantages in view the inventionembodies a frame having a traverse cylinder shaft journaled therein. aplurality of cone and tube carrying spindles journaled in arms andpositioned whereby cones and tubes formed thereon are aligned with andcontact the surfaces of the traverse cylinders and means for rotatingthe parts and elevating the spindles when a strand of yarn breaks andalso as the cones or tubes are filled.

Referring now to the drawings wherein like reference characters denotecorresponding parts the improved cone and tube winder of this inventionincludes a frame, generally indicated by the numeral it. a traverse orgrooved cylinder 1 i mounted on a shaft l2, a traverse arm l3 having abase it and reciprocated by a bar 55, a ratchet it which is actuated bya pawl ii, the movement of which is controlled by a yarn engaging lever18, and a yoke 15 in the end of arms 2!! and 2| of which cones or tubes,as indicated by the numeral 22 are held for winding.

Yarn, as indicated by the numeral 23 is fed from a bobbin 24 through atension 25 from which the yarn passes through an eye it on the end ofthe traverse arm is to grooves 2? of the cylinder It and from thecylinder the yarn is fed back and forth across the surface of a core 28which is freely held in the yoke i9.

Should the yarn break, the lever it moves u wardly allowing the pawl Hto engage the ratchet 56, causing the ratchet to rotate counterclockwiseto a point where an end 25 of the lever 23 engages the teeth of theratchet i5. locking the ratchet.

With the ratchet is turning counterclockwise a chain 30, attached to theratchet at tl e point %i and trained over a sprocket 32 on the yoke i9,turns the sprocket whereby a cone or tube in the arms of the yoke ismoved upwardly away from the surface of the cylinder so that rotation ofthe cone or tube ceases.

In the same movement a chain attached to the ratchet it at the point atone end to a lever at the other, actuates the lever 35 about a pivotillustrated in 7, 8 and 9 so that a pin 3'5, extended through a slot 38in the base M of the traverse arm It moves the pin 31 with the bar 39from which the pin extends upwardly whereby a ball i6 on the lower endof the bar 39 moved upwarcly out of a socket ii in the bar is so thatmovement of the traverse arm ceases. The traverse arm i3 is pivotallymounted by a pin 32 in a. bar

The traverse arm i3 is frictionaily held a socket M of the base i i andthe lower end of the base is provided with a plate 35 that is secured tothe base with screws Upon rethreading the winder the lever I8 is drawndownwardly and retained in this position with the yarn which extendsthrough the eye 23 and over the surlace oi the cylinder ii to the core2. 3.

The chain at is also connected to the yoke 19 in such a manner that as acone or tube builds up in the yoke the upward movement of the outer endsof the arms and 2! also actuates the ratchet i5, and this movement ofthe ratchet also withdraws the ball 4i} from the socket @l therebystopping the movement of the traverse arm H3.

The reciprocating movement of the traverse arm 13 is obtained by a leveris having a lot {39 therein and, as illustrated in Fig. 2, the lever Allis pivotally mounted on a pin on the end of a support 5!. The support 5iis mounted in a slot 52 in a vertical channel shaped member 53 of theframe with a bolt 54 whereby the stroke is adjustable to correspond withthe length of a cone or tube being formed. The upper end of the lever 38is pivotally connected to the oar [5 with a pin 55 and a ball 55 on thelower end extends into a spiral groove 5? in the surface of a cylinder58 and it will be noted that by moving the support 5% vertically thelength of travel of the upper end of the lever 1% is adjusted.

The cylinder 58 is mounted on a shaft 59 and the shaft is rotated by abelt or chain 68 which is trained over pulleys 6i and 52. The pulley (itis mounted on the shaft i2 and a belt 63, which is also trained over thepulley 6| extends from a motor pulley (it on a shaft 55 of a motor 66.

A motor H6 drives a belt conveyor 81 with a belt 68 and pulleys 89 andi9 and, as illustrated in Fig. 2, the belt extends through a trough Hwhereby cones, tubes, cores, and other parts may be conveyed to and fromthe machine.

5 As illustrated in Figs. 5 and 6 the traverse levers !8 are formed withextended ends I2 that are positioned to be engaged by the yarn 23, asshown in Fig. 1, and the opposite ends of the levers are provided withoffset sections I3 that enga the pawls H which operate the ratchet I6.From the offset sections I3 of the levers I8the levers are provided withsections 14 that extend from bases '35 through which the levers arepivotally mounted on a tranverse member I6 of the frame of the machineby pins TI. The pins I1 are positioned in fiat sections or bases 28 fromwhich the'sections I5 extend.

The ratchets I6 are mounted on a shaft I8 and the pawls I l are mountedby eccentrics I3 on a shaft 80 which is journaled on transverse members8| of the frame by bearings 82.

The pawls I! are resiliently held upwardly by springs 83 and similarsprings 84 urge the levers I8 upwardly against the yarn.

The shaft 80 isalso provided with a pulley or sprocket 85 over which thechain or belt 53 is trained whereby the shaft 80 is rotated by the motor66.

The traverse or grooved cylinders I I are formed, as illustrated in Fig.4 with complementary sections and the sections are provided with hubs 05on transversely disposed webs 3? and bolts 88 extend through the websfor securing the sections together. One of the hubs is provided with akey 89 by which the cylinders are keyed to the shaft I2.

As illustrated in Fig. 2 the cylinders are provided with pairs ofgrooves 21 and the grooves are positioned to correspond with the conesor tubes of different lengths, the pitch of the grooves being such thata groove extended from a point or vertex at the meeting point ofsections of the groove leads yarn into a groove extended from acorresponding point at the opposite end of the cylinder. By this meansthe yarn is then fed continuously back and forth across a cone or tubeas may be desired.

The yokes I9 in which the tubes or cones are held are provided with hubs90 which are provided with radially disposed openings 9|, as

shown in dotted lines in Fig. 2, and the hubs are -mounted on studs 92which extend from plates 93 that are provided with registering openingswhereby the arms of the yoke may be set at different angles tocorrespond with the angle of a cone to be formed. The yokes are retainedin adjusted positions by pins 94 that extend through the openings in thehubs and plates. The plates 03 are provided with extended arms 55between which the sprockets 32 are positioned and the arms are pivotallymounted on a bar 96 of the frame by shafts 91 which are journaled inbearings 98.

The extended ends of the arms 20 and 2! of the yoke I are provided withcylindrical hubs 99 and I00, respectively and, as illustrated in Fig.12, a frustro-conical shaped head I (H extended from the'hub I00 may bemanually withdrawn by a disc I02 extended from the opposite end of thehub when it is desired to remove and replace a cone or tube.

A similar head I03 is journaled on the end of the hub 99 with a ballbearing I04 that is mounted in the head and positioned on a stud Iextended from the end of the cylindrical hub. The head I 0| is alsojournaled on a shaft I 06 through a ball bearing I0'I that is mounted ona stud iiis'extended from the shaft. The opposite end of the shaft isprovided with a section 409 of reduced diameter and the disc I02 ispositioned on the end of the reduced section or stem 00. A spring H0 ispositioned around the shaft and with one end of the spring seatedagainst a stationary head III in the end of the hub and the otheragainst a pin H2 extended through the shaft I05, the shaft isresiliently urged longitudinally with the head IBI extended into and infrictional contact with a collar IIZa having a set screw Ilse therein,in the large end of a cone. By this means cores of tubes or cones areremovably mounted in the yoke It and cones or tubes formed on the coresmay be removed as theyare completed and replaced with conical orfrustro-conical shaped core members.

In the machine illustrated in Fig. 1, the parts are assembled to providea unit on each side of the center and, as illustrated in Fig. 2, aplurality of units may be used on each side of the center. With thepartsduplicated the reference numerals are applied to the unit on one side ofthe center only and it will be appreciated that the same referencenumerals may be applied to corresponding parts on the opposite side ofthe center.

However, the belt or chain 03 extended from the motor to the cylindercarrying shaft I2 may extend over the sprocket 85 on the shaft or thecylinder carrying shaft M3 on one side of the machine may be driven by achain or belt H4 from a pulley or sprocket on a motor I Hi.

The reciprocating bar I5 extends continuously through the unit of themachine and balls 40 of the traverse arms are freely positioned insockets, similar to the sockets A! in the bar. The bar may be slidablymounted in bearings I IT in the frame.

One of the shafts i2 is positioned on each side of the machine andyokes, similar to the yokes I9 are positioned upon the common centrallypositioned bar 05 whereby the yokes are free to swing vertically.

The yarn guiding grooves, as illustrated in Fig. 10, are oppositelypositioned and are in the form of a V with the vertex or point of the Vspaced from the ends of the cylinder and with the arms or sections atthe sides positioned on equal angles from a plane extended through thelongitudinal axis of the cylinder. The arms or sections of the groovesat the sides tapered out at points positioned between the vertices andthe termination of quadrants in which the section of the grooves arepositioned.

As an illustration the grooves of a cylinder if:

inches in diameter taper out at points positioned 4 inches from thevertex and also, as an illustration, the grooves are T33 of an inch wideby s of an inch deep at the vertex.

Furthermore, with the ten inch cylinder, as illustrated in the drawings,thirty-six inches of yarn is fed to the cone or tube with eachrevolution of the cylinder whereas in a conventional driving cylinder ofthree or three and onehalf inches in diameter about ten inches of yarnis fed to a cone or tube with each revolution, and should machines ofthis type be speeded up to wind thirty-six inches of yarn with the samecomparatively small feeding cylinders, the traverse or yarn guide wouldtravel so fast that it would be difficult to prevent breakage.

In using the large cylinder the amount of yarn supplied to the tubes andcones is increased without increasing the speed of the traverse or driveroll of the machine.

It will be understood, however, that these dimensions are only for thepurpose of illustration and the grooves may be iforrned-ofajsuitablesize in cross section and also of a suitable len th.

In the design illustrated in Figs. 15 and .16 a cylinder I29, similar tothe cylinder l I is mounted on a shaft i2! that is journaled in bearingsi22 and 23 in frame members l24 and [25, respectively and, as shown inFig. 15, the cylinder is provided with grooves i26 and i2! that extendfrom points or vertexes M8 and E29, respectively at the points where thegrooves are of greatest depth, to points I35 and BI, of the groove i238,and 32 and E33 of the groove I21, where the grooves taper out into thesurface of the cylinder.

The yarn, as indicated by the numeral I34 is fed to the groove andcylinder through an eye 35 at the vertex of a triangle of a yarn guide135 having converging arms that extend from a hub 13'? which is slidablymounted on a bar L38. The bar 233 is mounted in the frame members i2 3and 525 and this bar and also a bar I39 provide guiding means forretaining the yarn guide 35 in an upright position. The member 35 isprovided with a clip MB that extends around the bar 539, and the hub i3?is provided with a lug iti in which a follower N32 is carried. Thefollower M2 is provided with a boss I43 and a stud i i i which extendsfrom the boss is positioned in an opening in the lug MI, in which it isheld by a nut M5.

The follower M2 is positioned to travel in a traverse groove Hit of acylinder hit which is mounted on a shaft M8. The shaft I43 is journaledin the frame members 524 and I25 and the shaft may be driven from theshaft 12! by a belt i 39 which is trained over pulleys I50 and 554. Theshaft HE is driven by a belt 552 on a pulley 553, similar to the belt.53 and pulley 6|, of the type illustrated in Fig. 2.

In the design as illustrated in Figs. 2 and the pairs of grooves at theends of the cylinder are positioned for winding a 10 inch cone or tube,the next pair of grooves for winding an 8 inch cone or tube, and thegrooves at the center for winding a 6 inch cone or tube. It will beunderstood, therefore, that the grooves may be positioned at differentdistances on the cylinder whereby cones or tubes of different lengthsmay be formed.

With the cylinder and traverse combination as illustrated in Figs. and.16 the cylinder is provided with one V-shaped groove at each end and thegrooves are oppositely positioned so that the yarn is carried to the endof the cone or tube and started back with the grooves.

It will also be noted that the grooves of the traverse cylinder M? arepositioned to start the yarn guide in the reverse direction with acomparatively easy movement, the meeting ends of the grooves beingprovided with straight sections i5 5 and 55 and the cylinder beingprovided with blocks E56 and 957 that are positioned to be engaged bythe follower.

With the grooves formed in this manner the pitch of a groove at one endis such that in making one revolution the groove leads into acorresponding groove at the opposite end of the cylinder H. Furthermore,with the grooves formed in this manner the grooves lead the yarn to theend of the cone or tube and bring it back thereby forming tapered endsand at the same ime, in holding the yarn in tension the ends of cones ortubes formed on the machine are tight or firm.

It will be understood that modifications may be made in the design andarrangement'of the parts without departing from the spirit of theinvention.
